The mouse cerebellum regulates innate defensive neural circuitry by tonically controlling dopamine release in the periaqueductal gray, thereby modulating synaptic responses of the Chx10-positive neurons that generate freezing behavior.
When coupling between STN spikes and cortical gamma oscillations was strong, subsequent movement was initiated earlier, independent of changes in mean firing rates, demonstrating the importance of relative spike timing.
Novel transgenic zebrafish lines allow selective ablation of neuronal mitochondria by far red light, providing a powerful tool for investigating mitochondrial homeostasis in neurons and mitochondrial mechanisms in neurological disease.
An implantable device based on organic electrochemical transistors is developed for quantitative mapping of neurotransmitter release across multiple brain regions, revealing a cross-talk between the mesolimbic and nigrostriatal dopaminergic pathways.
Demonstrating extreme diversity across crustaceans while contrasting with evolutionary stability in insects, mushroom body homologues further underpin the unity of Pancrustacea and shed new light on arthropod brain evolution.
